The 2008 Copenhagen Consensus ranked micronutrient supplements as the top development priority out of more than 40 interventions considered. Specifically, vitamin A supplementation for children (every 4‐6 months, from age 6 months to 5 years) and therapeutic zinc supplementation for diarrhea (10‐14 days of supplementation, up to the age of 5) were considered. Vitamin A supplementation can reduce all‐cause mortality for children 6‐59 months by 23%, and several studies suggest that therapeutic zinc supplements for diarrhea can reduce diarrheal mortality below the age of five by 50%.
